Beit known that I EMANUEL HENRnrsoN,

a citizen of the United States, and a resident 'ofBridgeport, inthe-county of Faireld'and State o f Uonnecticut, haveinvented certainnew and luseful Improvementsin Double? Acting Ratchets, of which thefollowing is a specification. o

This invention relates ,to new and useful improvementsl in ratchets, andis" designed` with special reference'v to'` use upon boring mills,planers, and other machine-tools.

The feed-shafts of'machine-tools of the above class frequently requirea' slight vmovement for 4'the fine setting of adjustment of the'tool.

This has heretofore been vaccomplished in many instances by a*detachable hand-crank applied tothe end of the-shaft, which wasinconvenient and otherwise objectionable.

:It is therefore the 4purpose of my inven- .tion to provide an improveddouble-acting ratchet for making the several slight adjustments of thetool 'required at times; to design it as a-iixed attachment to thefeedshafts of the machine and adjacent to the saddle, thus convenientlto the operator; to construct it'as a lever-operating' device adaptedfor'engagement to operate in both a forward and backward 'direction andIhav- 'ing a normal intermediate disconnected position, which thetool-*automatically assumes when released.

`.Upon the accompanying drawings, forming afpart of this specification,similar characters o reference denote like or corresponding lpartsthroughout the several figures, and of Whichv `Figure 1 shows aperspective view of the face and end of a portion of a cross-rail andsaddle of a boring-mill with` a pair of my improved ratchets 'attachedto the feedf shafts and saddle. Fig. 2 shows, on an enlargedscaIe, aside elevationof my ratchet disconnected. Fig. 3 is a centrallongitudinal section' through the ratchet' and taken on line 3 3. ofFig.3. Fig.- 4 is a horizontal section .of the ratchet, taken on line 4 4 ofFig. 3, the operating-leveyho'wever, being shown in an engaged positionand the sleeve containing a square hole instead of `a round, as se'en inF1 s. 2 and-3. l V v eferring in detail to the characters of rin erencemarked u on'the'drawings, 1A

Both oftheseshafts are commonly used upon boring-mills, planers, andother.Inac'hinel -toolsand are driven through gear comico-- viouslyconstitute no part of my invention. X 1

The' ratchet- 'proper comprises an annular sleeve c; which maybeprovided-with either. a keyway b for attachment to a'shaft, as seeniii-Fig. 3,v or'may contain ,a shoulderedhole c, as seen'in Fig. 4.- Theformer construction is vobviously best adaptedforwround'L shafts, suchas are'shown in Fig. lgjwhile the 1 i other design isespecially adaptedfor squaredy l By this or an equivalentmeans the;

From the foregoing construction 'it W1l.lf,'l:3eseen that theactionv of the spring upon the plunger not only serves to normally holdit disengaged from the sleeve but also to hold its ends tight againstboth shoulders s of. the-lever, thus normally retaining the leverin anintermediate p osition ro straight in line with thear'm and movements ofthe plunger. This normal position of the parts leaves the' sleevedisengagedand free to turn' with the `o 4erati'ng movementsoiI the.shaft upon Whic it is mounted,'but always.

` in position to bel quickly operated by hand+ as, for instance,in thesettin of thetool yWhile the shafts are at rest an preparatory to'beginning-'Works vThis construction e'rmits of a movement of the sleeveand s aft zo in either direction by simpl operating the leverffcorresp'ondingly,. "L ein apparent that if the lever be thrust upwaras seen in full lines inxFi L4, the upper shoulders are engaged`and t eplunger operated a ainst the action of the spring to engage .an turn thesleeve in a'forwarddirection, While if it be similarly pressed intheoppositedirec- .tion (see dotted line, Fig.` 4) the plunger is similarlyoperated to engage the'sleeve, but

-3o turning it in the opposite direction.

This

. construction therefore forms a double-acting ratchet with an automaticrelease, comprising plunger, spring, and lever.

I t 'will of course be apparent tol those v y skilled-inthe art that myinvention isv equally quently I do not wish'to be applicable to manyother uses than that to which I have shown it ap lied, -and'conselimited in that respect. t, Having thus described my invention, what Iclaim, ancldesire` to secure by Letters Pat' ent, is-

1. Ina ratchet of the class described, the combination of a sleeve, anarm pivoted 'pivoted in the arm havinr principallybesid es the sleeve, asinglethereon, a spring-actuated plunger/mounted therein to engage thesleeve, a lever pivoted in the arm havin(1r shoulders engaged by the luner to norma l ret-ain the lever in an inl) g Y -termediateposition andadapted to operate the plunger by either a forward or backward jmovementot1 the lever.

2 In a ratchet of the class described, 'the combination `with a sleevehaving a` toothed or backward' shoulders engaged bythe plungertonormacllyl retain. the leverj in an intermediate position yand 'adapted't0 operate the plunger a ainst the actionof its spring by either aIorward or backward movement of itslever.l

` 4. In a ratchet of the class described, the combination with vasleeveadaptedfor engagement with ashaft, of an arm 'ivoted upon thesleeve-having a longitudina socket therein, a lunger mounted'in ythesocket and having a ivided head forming o positely-located shoulders, alever pivote in the varm vand having shoulders to registerwith those ofthe head of the lungerand a spring to@ shoulders engaged.
